So far, the generation and pumping using algae energy has not been able to escape the stage of fragmentary test operation. Countries around the world are focusing their efforts on developing renewable energy to replace fossil fuels and actively respond to climate change issues. Korea, which is surrounded by sea on three sides, has abundant marine energy resources, and it is urgently required to present a plan to utilize algae energy in various ways.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, the well-known functions or constructions are not described in order to simplify the gist of the present invention.

The pumped power generation convergence system using the tidal energy of the present invention is constructed by combining the seawater pumping power, the power generation, the fresh water and the fish culture system using the tidal current energy of the coast, and utilizing the abundant marine energy resources of the Republic of Korea .

In addition, the pumped power generation fusion system using the algae energy of the present invention minimizes the loss of head in the process of supplying the power source necessary for the operation of the pumping system and flowing the pumped water along the pipeline toward the storage tank .

FIG.

As shown in FIG. 1, the amphibious pumped power generation convergence system 1 using algae energy according to an embodiment of the present invention is constructed by integrating the seawater saline water, power generation, fresh water and fish style using coastal algae energy And is composed of three elements including the pumping device 10, the aquaculture device 20, the power generation device 30 and the desalination device 40 so that the abundant marine energy resources of the Republic of Korea surrounded by the sea can be used for multipurpose.

As shown in Figs. 1 and 2, the pumping device 10 is installed on the sea coast and converts the flow energy of the fluid into mechanical energy to pump seawater. The pumping device 10 includes piers 11, ).

The bridges 11 are provided in a cantilever type in which one end is fixed to the land and the other end is not supported and is projected toward the sea. The supply pipe T1 through which the seawater pumped by the pumping device 10 moves to the aquaculture apparatus 20 is coupled to the cantilever of the pier 11.

In one embodiment of the present invention, the pumping device 10 is of a type that reciprocally rotates about the vertical axis by the flow energy of the fluid. However, according to marine conditions such as the coastal terrain and the speed of the tidal current, a known pumping system such as a horizontal axis rotation or a vibration system may be installed alone or in combination. A detailed description of the pumping apparatus 10 will be given after the description of the aquaculture apparatus 20, the power generation apparatus 30 and the desalination apparatus 40.

1, the aquaculture apparatus 20 includes a reservoir 21, an auxiliary water pump 22, and a breeding tank 23, which are configured to produce fish using the seawater pumped to the pumping apparatus 10, .

The reservoir 21 is constructed to store the seawater pumped into the pumping apparatus 10 and is constructed to have a storage capacity capable of sufficiently storing the seawater pumped. The water storage capacity can be selected in conjunction with the pumping capacity of the pumping unit 10, the amount of breeding tank 23, and the generating capacity of the generator 31.

The pumped storage power generation convergence system (1) of the present invention is an integrated cascade production system for raising fish using pumped seawater or using water as drinking water through a desalination device (40) to produce electric energy. The system can be used in a complex way within the linkage system, thus enabling the economic activation of the coastal area and the support of the island area.

The power generation device 30, which will be described later, converts the potential energy of the seawater into electric energy, so that the reservoir 21 is installed at a position sufficiently higher than the pumping device 10.

As shown in FIG. 1, a desalination apparatus 40, which is a seawater desalination apparatus, may be installed in the storage tank 21.

Seawater desalination refers to a series of water treatment processes that remove high-purity drinking water, domestic water, and industrial water by removing dissolved substances including salt from living waters or industrial waters, which are difficult to use directly. It is also called seawater desalination, and the equipment used to produce seawater in fresh water is called seawater desalination.

When the desalination apparatus 40 is installed in the storage tank 21, the water in the storage tank 21 is converted into drinking water, domestic water or industrial water and supplied to the residents of the surrounding area through the discharge pipe T3.

Therefore, if the pumped storage power convergence system (1) of the present invention is constructed in an inter-mountainous region or an island region with limited water access, it is possible to simultaneously solve the problems of drinking water, domestic water and industrial water, . In addition, electricity required during the desalination of the seawater can be supplied from the power generation device 30 and can be an independent system.

As shown in FIG. 1, the auxiliary water pump 22 is configured to pump groundwater to the storage tank 21, where groundwater includes underground fresh water and underground water.

The coastal aquaculture seawater farms in Korea are operated by taking seawater directly, which causes frequent damages every year due to red tides, abnormal currents, oil spills, and the like. A large maintenance cost is required.

Underground seawater is reported to have a constant water temperature of about 15 ℃ in winter. Therefore, when the underground seawater is pumped and supplied to the breeding tank 23 together with the seawater pumped by the pumping device 10, it is necessary to maintain the temperature of the breeding tank 23 during the winter season and the summer season, There is an advantage of drastically reducing the huge maintenance cost.

On the other hand, if the underground fresh water is pumped to the auxiliary water pump 22 for drinking water, domestic water, and industrial water, the downsizing and maintenance cost of the desalination plant can be expected to be reduced. In addition, the auxiliary water pump 22 can receive the necessary electricity from the electricity generating device 30, and can be an independent system.

As shown in Fig. 1, the breeding tank 23 is a structure for breeding fish, and mixed seawater and underground seawater are supplied in the reservoir 21. [ When the temperature of the breeding tank (23) is kept constant at about 17 ~ 18 ° C due to the supply of the underground seawater, the breeding environment of the cold water fishes such as the catch fishes and trout can be kept good.

The clean seawater in the storage tank 21 is continuously introduced into the breeding tank 23 so that the water for raising the fish in the breeding tank 23 is maintained in the best condition for water quality and temperature. The water drained in the breeding tank 23 is discharged to the power generation device 30 side through the drainage pipe T2.

As shown in Fig. 1, the power generation apparatus 30 is configured to generate power by converting the potential energy of seawater discharged from the aquaculture apparatus 20 into mechanical energy, and is installed at a lower waterfront than the aquaculture apparatus 20. Fig.

The power generation device 30 includes a generator 31, aberration 32, and a power converter 33. [ The sea water drained through the drain pipe (T2) in the aquaculture device (20) is used to produce power by rotating the aberration (32) and then drained to the sea. The electric power generated by the generator 31 is supplied to an inter-mountain area or an island house, a home, a factory, etc. through a power converter 33 via electric wires.

In the following, a detailed description of a pumping device (hereinafter referred to as a " reciprocating pumping device ") will be described.

As shown in Figs. 2 to 4, the reciprocating pumping device 10 is made such that only the minimum configuration in which the supply of the power source necessary for operation is minimized and the lift is formed by the flow energy is arranged inside the fluid, A first amphibious unit 100, a second amphibious unit 200, a first interlocking unit 300, and a second interlocking unit 400.

 The first amphibious unit 100 and the second amphibian unit 200 are configured to independently pump the seawater by using the flow energy of the fluid and the first interlock unit 300 and the second interlock unit 400 Rotational force is transmitted to each other. Therefore, even when the first interlocking unit 300 and the second interlocking unit 400 are not installed, the first amphibious unit 100 and the second amphibious unit 200 can respectively pump seawater, (100) may be separately installed. L represents the flow direction of the algae.

2 to 4, the first amphibious unit 100 includes a first wing member 110, a first rotating unit 120, a first arm 130, and a first cylinder 140 .

The first wing member 110 is disposed below the water surface and forms a lift by the flow energy of the algae. The first wing member 110 has a substantially wing shape and is streamlined in plan view (see FIG. 4).

The front end portion of the first wing member 110 is thicker than the rear end portion in a plan view (see FIG. 4), and the first wing member 110 is arranged so that the current flows from the front end portion toward the rear end portion. In other words, the front end portion is disposed upstream of the rear end portion based on the flow of the algae.

The rotation axis 111 of the first wing member 110 is formed in the longitudinal direction and extends outwardly of the fluid.

As shown in FIGS. 2 and 3, the first rotating means 120 is configured to reciprocally rotate the first wing member 110, and is provided with a motor rotating in both directions by a control unit (not shown).

The first rotating means 120 transmits a periodic bi-directional rotational force to the rotating shaft 111 of the first wing member 110 while being coupled to the end of the first arm 130. The rotation axis of the first rotation means 120 may be directly connected to the rotation axis 111 of the first wing member 110 or may be transmitted by a gear or a pulley.

As shown in FIG. 3, the first rotating means 120 rotates the rotating shaft 111 of the first wing member 110 on the water surface. The first wing member 110 is periodically rotated in both directions by the first rotating means 120 so that the direction of lift generated in the first wing member 110 is periodically switched.

The first arm 130 is configured to be reciprocally rotated about the first rotation center axis A1 by lifting force of the first wing member 110 and is formed in a long bar shape. The first arm 130 is provided outside the fluid, and the rotation axis 111 of the first wing member 110 is rotatably coupled to the end of the first arm 130.

The first rotation center axis A1 is a longitudinal axis and is rotatably installed on a fixed object. 2 to 4, the fixed object is shown as a first plate W1 and a second plate W2. As shown in Fig. 2, the first plate W1 and the second plate W2 are coupled to the end of a pier 11 constructed on the shore for fixing the pumping device 10. [

As shown in FIG. 5, the first cylinder 140 has a structure in which the fluid flows in and out by periodically increasing or decreasing the internal pressure due to the reciprocating movement of the first piston 144, And is connected to the first arm 130 by the first connecting rod R1.

4 and 5, the first arm 130 is rotated in the horizontal direction about the first rotational center axis A1 in the longitudinal direction, and the first piston 144 is rotated about the first rotational center axis A1 , I.e., in the horizontal direction.

The first connecting rod Rl is configured to convert the rotational motion of the first arm 130 into the reciprocating motion of the piston, and both ends thereof are rotatably connected to the first arm 130 and the first piston 144, respectively .

The first connecting rod is moved up and down as the pendulum is swung to the left and right as the pendulum is connected to the first piston 144 when the first arm 130 rotates, To the reciprocating motion of the piston.

As shown in FIG. 5, the first cylinder 140 includes a body 141, an inlet 142, and an outlet 143.

The body 141 is formed in a cylinder shape, and the internal pressure of the first piston 144 is increased or decreased by the reciprocating movement of the first piston 144.

5 (a), when the first piston 144 moves toward the first connecting rod R1, the pressure inside the body 141 decreases, and as shown in Fig. 5 (b) When the first piston 144 moves to the opposite side of the first connecting rod R1, the pressure inside the body 141 increases.

When the pressure inside the body 141 is reduced, the seawater flows into the body 141 through the inlet 142. When the pressure inside the body 141 is increased, the seawater flows through the outlet 143 into the body 141 ).

The first check valve C1 is installed in the inlet 142 and the second check valve C2 is installed in the outlet 143. [ The first check valve (C1) and the second check valve (C2) are configured to selectively block the passage of seawater by the movement of the ball.

5 (b), the first check valve C1 prevents the passage of the inside of the inlet portion 142 when the internal pressure of the body 141 increases, so that the flow of the sea water through the inlet portion 142 5A, the second check valve C2 blocks the passage inside the outflow portion 143 when the internal pressure of the body 141 is reduced, so that the outflow portion 143 ) To prevent the inflow of seawater.

Although not shown, one end of a pipe or a hose (hereinafter referred to as a 'channel') through which seawater moves is coupled to the inlet G1 of the inlet 142. And the other end of the channel connected to the inlet G1 is located below the water surface.

Although not shown, one end of the channel through which the seawater moves is also coupled to the outlet G2 of the outlet 143. The other end of the channel connected to the outlet G2 is connected to a reservoir 21 for storing the seawater.

The seawater pumped by the reciprocating motion of the first piston 144 moves toward the reservoir 21 from the inside of the pipeline when the pressure inside the first cylinder 140 increases in the process of moving to the storage tank 21, When the pressure inside the pipe 140 decreases, it stagnates inside the pipe. Such a periodic congestion of water can cause the loss of head in the pipeline to increase and the amount of water to be pumped can be reduced.

2 to 4, the first cylinder 140 and the first connecting rod R 1 are each provided in a pair, and the pair of first connecting rods R 1 are connected to the first rotating center shaft The first arm 130 may be rotatably coupled to the first arm 130 on both sides thereof. Although not shown, the fluids respectively flowing out from the pair of first cylinders 140 through the outlet G2 are combined in the main pipe and moved to the reservoir 21. [

When the first connecting rod R 1 is rotatably coupled to the first arm 130 on both sides of the first rotational center axis A 1 relative to the first rotational center axis A 1, The reciprocating motion of the first piston 144 connected to the first connecting rod Rl forms a phase difference of one-half of the cycle with respect to the first cylinder 140, The increase and decrease of the internal pressure of the liver are reversed.

Accordingly, the fluids respectively flowing out from the pair of first cylinders 140 through the outlet G2 are merged at the main pipe while forming a phase difference of one-half of the cycle, and the fluid merged at the main pipe is continuous Flow. The continuous water flow has the advantage that the amount of water to be pumped is increased by reducing the loss head in the pipeline.

The front end portion of the second wing member 210 is thicker than the rear end portion in a plan view (see FIG. 4), and the second wing member 210 is arranged so that the algae flows from the front end portion to the rear end portion.

The rotation axis 211 of the second wing member 210 is formed in the longitudinal direction and extends outwardly of the fluid.

As shown in FIGS. 2 to 4, the second amphibious unit 200 is provided symmetrically with the first amphibian unit 100, and operates substantially on the same principle as the first amphibian unit 100. Therefore, the detailed description of the second rotating unit 220, the second arm 230, and the second cylinder 240 is substantially duplicated with the first transfer unit 100, so it is omitted.

Reference numeral R2 is a second connecting rod, 241 is the body of the second cylinder 240, 242 is the inlet of the second cylinder 240, and 243 is the outlet of the second cylinder 240.

Although not shown in the drawing, the fluids respectively flowing out from the pair of first cylinders 140 and the pair of second cylinders 240 through the outlet G2 are merged in the main pipe and moved to the reservoir 21 .

Referring to FIG. 4, in the first and fourth cylinders 140A, the internal pressure increases in the second cycle and the third cycle, and the fluid flows out to the main pipe. In the first cycle and the fourth cycle, It does not leak to the main.

In the first cycle and the fourth cycle, the internal pressure of the first and second cylinders 140B and 140B is increased so that the fluid flows out to the main pipe do.

On the other hand, the second-1 cylinder 240A increases the internal pressure in the first period and the second period to discharge the fluid to the main pipe. In the third period and the fourth period, the internal pressure decreases and the fluid flows out to the main pipe Do not.

In the second and second cylinders 240B, the internal pressure decreases in the first period and the second period, so that the fluid does not flow out to the main pipe. In the third period and the fourth period, the internal pressure increases and the fluid flows out to the main pipe do.

Accordingly, the fluids discharged from the pair of first cylinders 140 and the pair of second cylinders 240 through the respective outlets G2 form a phase difference of 1/4 of one another, And the combined seawater in the main pipe forms a continuous flow. Continuous seawater flow has the advantage of reducing the loss head in the pipeline and increasing the amount of seawater being pumped.

7, the rotary shaft 111 of the first wing member 110 and the first rotation center axis A1 may be arranged in the horizontal direction in the reciprocating rotary pump device 10 '.

The first wing member 110 is reciprocally rotated in the vertical direction with respect to the first rotation center axis A1 so that the first rotation unit 120, the first arm 130, and the first cylinder 140 All are placed under water.

The reciprocating rotary pumping device 10 'shown in FIG. 7 has a structure in which the rotary shaft 111 of the first wing member 110 and the first rotary center axis A1 are arranged in the horizontal direction, 2 to 4, except that the arm 130 rotates reciprocally, sharing the first central axis of rotation A1.

According to the present invention, by providing a facility in which the pumping device, the aquaculture device and the power generation device sequentially operate in conjunction with each other in the coastal area, a system in which seawater is pumped, It is possible to provide a pumped-water power generation convergence system using algae energy that can utilize the abundant marine energy resources of the Republic of Korea surrounded by the sea on three sides in a multipurpose manner.

Further, it is possible to provide a pumped power generation convergence system using algae energy, in which the interlocking unit transmits the rotational force of one arm to the rotational axis of the other wing member, so that the supply of the power source necessary for operation of the pumping unit is minimized.

Further, as the pair of first connecting rods are rotatably coupled with the first arm on both sides with respect to the first rotational center axis, in the course of the flow of the pumped water along the pipeline toward the reservoir, the loss of head Can be minimized by using the tidal energy.

In addition, since the rotation axis of the first wing member is rotatably deflected from the first arm outside the fluid, only the minimum configuration for generating lift by the flow energy in the pumping device is disposed inside the fluid, It is possible to provide a pumped-water power generation convergence system using algae energy which is made to prevent decrease in the water-pumping efficiency caused by the pumping energy.
